Gamma-Ray Burst Progenitors [PDF]
Space Science Reviews, 2016 We review our current understanding of the progenitors of both long and short duration gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use three distinct strands; (i) direct observations of GRBs and their host ...

Neutrinos from the Brightest Gamma-Ray Burst? [PDF]
Astrophysical Journal Letters, 2022 We discuss implications that can be obtained by searches for neutrinos from the brightest gamma-ray burst (GRB), GRB 221009A. We derive constraints on GRB model parameters such as the cosmic-ray loading factor and dissipation radius, taking into account ...

The Fermi-GBM Gamma-Ray Burst Spectral Catalog: 10 yr of Data [PDF]
Astrophysical Journal, 2021 We present the systematic spectral analyses of gamma-ray bursts (GRBs) detected by the Fermi Gamma-Ray Burst Monitor during its first ten years of operation.

Evidence for an intermediate-mass black hole from a gravitationally lensed gamma-ray burst [PDF]
Nature Astronomy, 2021 If gamma-ray bursts are at cosmological distances, they must be gravitationally lensed occasionally1,2. The detection of lensed images with millisecond-to-second time delays provides evidence for intermediate-mass black holes, a population that has been ...

Science, 2012 Stellar Explosions Stars that are born with masses greater than eight times that of the Sun end their lives in luminous explosions known as supernovae. Over the past decade, access to improved sky surveys has revealed rare types of supernovae that are much more luminous than any of those that were known before.

Particles, Strings and Cosmology (PASCOS 99), 2000 Ultra-high-energy, >10^19 eV, cosmic-ray and high energy, ~10^14 eV, neutrino production in GRBs is discussed in the light of recent GRB and cosmic-ray observations. Emphasis is put on model predictions that can be tested with operating and planned cosmic-ray and neutrino detectors, and on the prospects of testing for neutrino properties.

The Structure of Gamma Ray Burst Jets
Galaxies, 2022 Due to relativistic bulk motion, the structure and orientation of gamma-ray burst (GRB) jets have a fundamental role in determining how they appear.

A Roadmap to Gamma-Ray Bursts: New Developments and Applications to Cosmology
Galaxies, 2021 Gamma-ray bursts are the most powerful explosions in the universe and are mainly placed at very large redshifts, up to z≃9. In this short review, we first discuss gamma-ray burst classification and morphological properties.

The Fourth Fermi-GBM Gamma-Ray Burst Catalog: A Decade of Data [PDF]
Astrophysical Journal, 2020 We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi’s Gamma-ray Burst Monitor (Fermi-GBM). It extends the six year catalog by four more years, now covering the 10 year time period from trigger enabling on 2008 ...

Critical Tests of Leading Gamma Ray Burst Theories
Universe, 2022 It has been observationally established that supernovae (SNe) of Type Ic produce long duration gamma-ray bursts (GRBs) and that neutron star mergers generate short hard GRBs.
